ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) 7.
Verifying the EDG operates for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, a)
The EDG shall be loaded to the continuous rating (4150-4250 kw**) for the time required to reach engine temperature equilibrium, at which time the EDG shall be loaded to an indicated target value of 4676 kw (between 4600-4700 kw *) and maintained for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, a

During the remaining 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> of this test, the EDG shall be loaded to an indicated 4150-4250 kw**.
c)
During this test the steady state voltage and frequency shall be maintained at 7200 1 720 volts and 60 1 1.2 Hz.
8.
Verifying that the auto-connected loads to each EDG do not exceed the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating of 4548 kw.
9.
Verifying the EDG's capability to:
a)
Synchronize with the offsite power source while the generator is loaded with its emergency loads upon a simuisted restoration of offsite power, b)
Transfer its loads to the offsite power source, and c)
Be restored to its standby status.
10.
Verifying that with the diesel generator operating in a test mode, connected to its bus, a simulated safety injection signal overrides the test mode by (1) returning the diesel generator to standby operation and (2) automatically energizes the emergency loads with offsite power.
11.
Verifying that the fuel transfer pump transfers fuel from each fuel storage tank to the day tank of each diesel via the installed cross connection lines.
12.
Verifying that the automatic load sequence timer is OPERABLE with the interval between each load block within i 10% of its design interval.
13.
Verifying that the following diesel generator lockout features prevent diesel generator starting only when required:
a.
Barring Device b.
Remote-Local-Maintenance Switch 14.
Verifying that within 5 minutes of operating the diesel generator for at least I hour at a load of 4150-4250 KW** the diesel starts on the auto-start signal (Lnss of Off-Site Power signal), ener-gizes the emergency busses with permanently connected loads
- This band is meant as guidance to avoid routine overloading of the engine.
Loads in excess of this band shall not invalidate the test.

ELEDTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) within 10 seconds, energizes the auto-connected shutdown loads through the load sequencer, and operates for greater than or equal to 5 min-utes while its generator is loaded with the shutdown loads.
After energitation of these loads, the steady-state voltage and frequency shall be maintained at 7200 1 720 volts and 60 1 1.2 Hz.
h At least once per 10 years cr af ter any modifications which could affect diesel generator interdependence by starting the diesel generators simultaneously, during shutdown, and verifying that the diesel generators accelerate to at least 504 rpm in less than or equal to 10 seconds.
i.
At least once per 10 years by:
1.
Draining each fuel oil storage tank, removing the accumulated sediment and cleaning the tank using a sodium hypochlorite solution or its equivalent, and 2.
Performing a pressure test of those portions of the diesel fuel oil system designed to Section III subsection N0 of the ASME Code at a test pressure equal to 110 percent of the system design pressure.
4.8.1.1.3 Reports - All diesel generator failures, valid or non-valid, shall be reported to the Commission in a Special Report pursuant to Specification 6.9.2 within 30 days.
Reports of diesel generator failures shall include the information recommended in Regulatory Position C.3.b of Regulatory Guide L108 Revision 1. August 1977.
If the number of failures in the last 100 valid tests (on a per diesel generator basis) is greater than or equal to 7, the report shall be supplemented to include the additional information recommended in Regulatory Position C 3.b of Regulatory Guide 1.108, Revision 1, August 1977.

- Tests
- Test Frequency
$1 14 Once per 31 days 12**
15 Once per 7 days
- Criteria for determining number of failures and number of valid tests shall be in accordance with Regulatory Position C.2.e of Regulatory Guide 1.108, but determined on 6 per diesel generator basis.
For the purposes of determining the required test frequency, the previous test failure count may be reduced to zero if, in conjunction with the manu-facturer a complete diesel overhaul to like-new conditions is completed, and if acceptable reliability has been demonstrated.
The reliability crite-rion shall be the successful completion of 14 consecutive tests in a single series.
Ten of these tests shall be in accordance with Surveillance Require-ment 4.8.1.1.2.a.3 and 4.8.1.1.2.a.4; four tests, in accordance with Surveillance Requirement 4.8.1.1.2,f.
If this criterion is not satisfied l
during the first series of tests, any alternate criterion to be used to transvalue the failure count to zero requires NRC approval.
- The associated test frequency shall be maintained until seven consecutive failure free demands have been performed and the number of failures in the last 20 valid demands has been reduced to one.
